    • Method Detail

      • restart

        public SupervisorStrategy.Restart$ restart()
        Java API: Returning this directive discards the old Actor instance and replaces it with a new, then resumes message processing.
        Returns:
        (undocumented)
      • stop

        public SupervisorStrategy.Stop$ stop()
        Java API: Returning this directive stops the Actor
        Returns:
        (undocumented)
      • escalate

        public SupervisorStrategy.Escalate$ escalate()
        Java API: Returning this directive escalates the failure to the supervisor of the supervisor, by rethrowing the cause of the failure, i.e. the supervisor fails with the same exception as the child.
        Returns:
        (undocumented)
      • defaultDecider

        public final scala.PartialFunction<java.lang.Throwable,​SupervisorStrategy.Directive> defaultDecider()
        When supervisorStrategy is not specified for an actor this Decider is used by default in the supervisor strategy. The child will be stopped when ActorInitializationException, ActorKilledException, or DeathPactException is thrown. It will be restarted for other Exception types. The error is escalated if it's a Throwable, i.e. Error.
        Returns:
        (undocumented)
      • defaultStrategy

        public final SupervisorStrategy defaultStrategy()
        When supervisorStrategy is not specified for an actor this is used by default. OneForOneStrategy with decider defined in defaultDecider().
        Returns:
        (undocumented)
      • stoppingStrategy

        public final SupervisorStrategy stoppingStrategy()
        This strategy resembles Erlang in that failing children are always terminated (one-for-one).
        Returns:
        (undocumented)
      • seqThrowable2Decider

        public scala.PartialFunction<java.lang.Throwable,​SupervisorStrategy.Directive> seqThrowable2Decider​(scala.collection.immutable.Seq<java.lang.Class<? extends java.lang.Throwable>> trapExit)
        Implicit conversion from Seq of Throwables to a Decider. This maps the given Throwables to restarts, otherwise escalates.
        Parameters:
        trapExit - (undocumented)
        Returns:
        (undocumented)
      • makeDecider

        public scala.PartialFunction<java.lang.Throwable,​SupervisorStrategy.Directive> makeDecider​(scala.collection.immutable.Seq<java.lang.Class<? extends java.lang.Throwable>> trapExit)
        Decider builder which just checks whether one of the given Throwables matches the cause and restarts, otherwise escalates.
        Parameters:
        trapExit - (undocumented)
        Returns:
        (undocumented)
      • makeDecider

        public scala.PartialFunction<java.lang.Throwable,​SupervisorStrategy.Directive> makeDecider​(java.lang.Iterable<java.lang.Class<? extends java.lang.Throwable>> trapExit)
        Decider builder which just checks whether one of the given Throwables matches the cause and restarts, otherwise escalates.
        Parameters:
        trapExit - (undocumented)
        Returns:
        (undocumented)
      • makeDecider

        public scala.PartialFunction<java.lang.Throwable,​SupervisorStrategy.Directive> makeDecider​(scala.collection.Iterable<scala.Tuple2<java.lang.Class<? extends java.lang.Throwable>,​SupervisorStrategy.Directive>> flat)
        Decider builder for Iterables of cause-directive pairs, e.g. a map obtained from configuration; will sort the pairs so that the most specific type is checked before all its subtypes, allowing carving out subtrees of the Throwable hierarchy.
        Parameters:
        flat - (undocumented)
        Returns:
        (undocumented)
      • sort

        public scala.collection.immutable.Seq<scala.Tuple2<java.lang.Class<? extends java.lang.Throwable>,​SupervisorStrategy.Directive>> sort​(scala.collection.Iterable<scala.Tuple2<java.lang.Class<? extends java.lang.Throwable>,​SupervisorStrategy.Directive>> in)
        Sort so that subtypes always precede their supertypes, but without obeying any order between unrelated subtypes (insert sort).

        INTERNAL API

        Parameters:
        in - (undocumented)
        Returns:
        (undocumented)
      • withinTimeRangeOption

        public scala.Option<scala.concurrent.duration.Duration> withinTimeRangeOption​(scala.concurrent.duration.Duration withinTimeRange)
      • maxNrOfRetriesOption

        public scala.Option<java.lang.Object> maxNrOfRetriesOption​(int maxNrOfRetries)
